These are some of his oldest releases, they are pretty easy to get a hold of though. A lot of his older works were reissued two and three times since the original release. Usually there is a 32ATC-*/30ATC-* and TKCA version. Arion also came in a box called "Winds and Seeds" that contains the original soundtrack and symphonic versions of Nausicaa, Laputa and Arion. It's a beautiful box set should you ever have the opportunity to get one.
